2. Cross multiplication method.

(13/2) + (11/12) using LCM Method:
What is 13/2 plus 11/12 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 13/2
Fraction B: 11/12

What to be found?
(13/2) + (11/12) = ?
Find what's the sum of 13/2 and 11/12.

step 2 Compare the denominators of fractions 13/2 and 11/12 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 13/2 and 11/12 are not equal, it is said to be unlike fractions addition.

step 3For unlike fractions addition, find the LCM (least common multiple) of both denominators of fractions 13/2 and 11/12:
The LCM of 2 and 12 is 12.

step 4 Write the fractions 13/2 and 11/12 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 13/2 + 11/12
= [(13 x 12)/(2 x 12)] + [(11 x 12)/(12 x 12)]

step 5 Simplify the expression to have common denominator:
= 78/12 + 11/12

step 6 Take the common values out and rewrite the above expression like the below:
= 1/12 x (78/1 + 11/1)
= 1/12 x (78 + 11)

step 7Simplify the above expression further:
= 1/12 x 89
= 89/12
13/2 + 11/12 = 89/12

Hence,
13/2 plus 11/12 as a fraction is 89/12.
